CAR STRUCTURE.

Specification of Letters Patent.

Patented May 6, 1919.

Application filedOetober 10, 1918. Serial no. 257,590.

To all whom it may concern:

Be it known that I, HERMAN C. Pnrnnn, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car Structures, of which the following is a full, clear, concise, and exact description.

My invention relates to cars and, in one aspect, particularly to those cars, such as freight cars, that employ reinforcing posts upon the ends thereof. In such structure there are two reinforcing posts upon each end of the car andthere has also been provided a dead block located at the lower ends of each pair of reinforcing posts to receive the blows of coupler horns.

In accordance with one feature of my invention I form each pair of reinforcing posts and the associated dead blockin two substantially equal and symmetrically related parts each of semi-U-shape. These parts are assembled in the form of a U, the sides of each U constituting the reinforcing posts and the base of such U constituting the dead block. By means of this construction the force of the coupler blows is not only received by the dead block but is transmitted from the dead block to the reinforce ing posts each integrally formed in one piece with one-half of thedead block. This construction also serves to prevent distortion of the end of the car equipped with it in a direction transverse to the car.

In accordance with another feature of the invention, the base of the -U, whetherfthe U be formed in two pieces or not,is provided with a cap plate that receives the coupler blows and transmits them not only to the base or dead block ofthe U but to the end sill directly. I believe this feature is novel in relation to the dead block and apart from the reinforcing posts. i

The invention has, as another characteristic, the provision of an improved assembly of the upper ends of the'reinforcing posts with the car structure whereby the ends and sides of the car structure may not be distorted from their proper relation consequent upon coupler blows.

I will explain my invention more fully by reference to the accompanying drawings showing the preferred embodiment thereof and in which Figure 1 is an end view of a car equipped in accordance with my invention; Fig. 2 is a view on line 22 of Fig. 1;

Fig. 3 is a view on line 3-3 of Fig. 1; Fig. 4 is a perspective view, the novel features of the invention being includedxin the construction shown by full lines; Fig. 5 is a sectional view on line 5-5 of Fig. 3; and Fig. 6 is a sectional view on line 6-6 of Fig. 5.

Like parts are indicated by similar characters of reference throughout the different figures.

The body of the car illustrated includes center. sills 1, that are usually wooden, an end sill 2 at each end of the car, draft arms 3 beneath the center sills, and a coupler supporting strap 4: in conjunction with each pair of draft arms at each end of the car. Any suitable form of draft gear may be employed, such as that illustrated at 5, there being such a draft gear at each end of the car, each such gear being supported by the contiguous pair of draft arms 3. Each draft gear includes a coupler stem 6 and a coupler horn 7, the coupler stem being supported at its outer end by the adjacent strap 4. The tops of the draft arms 3 are desirably provicled with outsetting transversely arranged flanges 3, each strap 4 pertaining to each pair of draft arms being preferably of U- shape and also having outsetting transversely arranged flanges i that are bolted into assembly with the flanges 3. These straps, in this way,-serve'to assemble the pairs of draft arms into a unitary car strengthening structure. Upright posts 8 are disposed upon'the outer face of each end 9 of the car to reinforce the internal construction of thecar. Each post is integrally formed with one half of the dead block 10 that is bolted to the flanges 3 of the draft arms and the flanges 4 of the straps 4. Each post with its half of the dead block is symmetrically assembled with the other post and its half of the dead block to form a structure of U-shape. This construction enables meto use shorter stock and is therefore economical. The dead blocks receive the force of the blows of the coupler horns, being located in front of the end sills 2 and the center sills 1, whereby force of the blows of the coupler horns is transmitted through the dead blocks and the end sills to the center sills, these end sills and center sills serving to prevent shearing of the bolts that are relied upon to assemble the deadblocks with the draft arms and coupler supporting straps. By forming the halves of the dead blocks 10 and the external upright posts 8 integrally the force of the coupler blows is also transmitted to said posts 8 and therethrough to other portions of the car structure that are back of said posts. The further advantage which is realized by forming the posts and the dead blocks integrally resides in the cooperation of these elements to prevent material twisting or torsional movements of the ends of the car structure, a result which is enhanced by also :uniting the draft arms and yoke supporting straps with the dead blocks.

The 'cap plate :10. is anchored to the end sill 2 by bolts 10 :at a place above the dead blocklO. This cap p'lateextends rearwardly beyond 'the dead block to the end sill and overlies the dead block and therefore initially receives the force of the coupler blows which are transmitted not only through the deadblock-to'the end sill but are transmitted directly through the cap plate that is :along side of the dead block to the end sill. The force o-f the coupler blows is thus divided between the "dead block and the cap plate. The cap plate has-a poition 10 that underlies the dead block, the forward portion of the cap plate being thus formed into a pocket that receives the dead block. This cap plate -not-on=ly serves toreceive the force of the coupler blows but, in the event that the dead block is formed in two parts, also serves to maintain the parts of the dead block in ailinement and to,preserve the parts of the dead block in proper relation to both posts-8. The assembly *of the cap plate with the two parts of the dead block is further effected by means of the upright bolts 10* that pass through the adjacent strap 1, the top and bottom walls of the pocket that receives the dead block and the web portion of this-dead block. These bolts serve to clam-p these parts through which they pass in firm assembly.

The upper end of each post 8 is embraced by a U-bolt 12 whose base engages the outer face of such post. The branches of each U-bolt are held from spreading by plates or straps 13 through which the sides of the U-bdlts pass. There is desirably one strap for each of the U-bo'lts at each end of the car but the invention is not to belimited to this arrangement. The vouter branch of each U-bolt is desirably elongated and obliquely deflected as indicated at 1 1. The outer end of each U-bolt extension 14 is held in engagement with a bracket 15 by a nut 15, this bracket being secured to a side of the car within the car. By means of the structure 12, 13, 14 the reinforcing posts 8 are clamped close to the end wall 16 of the car and by means of the obliquely extended branches 14 of the U-bolts the sides of the car are maintained in ,proper relation with the ends of the car.

By means of the desired construct-ion at the top of the car the upper part of the ear is prevented from being deflected laterally or longitudinally and obliquely with respect to the lower part of the car to any material or injurious extent.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made Without =departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secureby Letters Patent the following l.
